Optional Port Module Card
Some Dell Precision and OptiPlex systems have the possibility of installing an optional port module card. This could be for an additional VGA, HDMI, USB-C, DVI, Serial Port, etc. This is because the systems do not have these ports available on the system board.
Check the Service Manual for your system model to verify if this option is available:
